A scuba safety stop is a pause during ascent that many recreational training programs teach as an added precaution on suitable dives. It can provide extra time for a controlled ascent, but it is not a guarantee against decompression illness and is not interchangeable with a required decompression stop.
When is a safety stop used?
Training agencies and dive computers may recommend a stop based on the dive profile and applicable guidance. The common practice of stopping near 5 metres/15 feet for a few minutes is widespread, but the precise recommendation depends on training, conditions, and the equipment or planning system used. Follow the procedure taught in your course and shown by your dive computer.
Safety stop versus decompression stop
A safety stop is generally a precautionary measure on dives planned within no-decompression limits. A required decompression stop is part of a decompression obligation and must be followed according to the dive plan and training. Never skip a required stop or use a safety stop as a replacement for decompression planning.
How to make a controlled stop
- Monitor depth and ascent rate using your instruments.
- Maintain neutral buoyancy and stay aware of your buddy and surroundings.
- Keep breathing normally and never hold your breath during ascent.
- Follow your dive computer and training, and adapt to currents or conditions as taught.
What if conditions make a stop difficult?
Do not create a more serious hazard by fighting a strong current or losing contact with your buddy. Follow your training and dive plan for the actual situation. If you have concerns about a dive profile, discuss it with your instructor before entering the water.
Bottom line
A safety stop is a useful precaution when appropriate, but no stop eliminates all risk. Plan conservatively, ascend under control, and follow your training and dive computer guidance.
Why scuba divers make safety stops
A safety stop is a planned pause at a shallow depth near the end of a dive, commonly included in recreational dive plans as an additional conservative practice. It gives the body more time to eliminate inert gas, but it does not guarantee that decompression illness will not occur. Whether a stop is recommended or required depends on the dive profile, computer guidance, training, and conditions.
How to perform a stop responsibly
Follow your dive computer and training-agency procedures for depth and duration. Maintain neutral buoyancy, monitor your gas supply, keep track of your buddy, and stay aware of waves, current, boat traffic, and nearby obstacles. Do not hold your breath or ascend rapidly just because the stop is complete. If conditions make the planned stop difficult, follow your training and the computer’s instructions for a safe response.
Safety stops are not a substitute for planning
Do not use a safety stop as permission to exceed depth, time, or gas limits. A dive computer, conservative profile, proper ascent, and adequate gas reserve remain essential. Learn how your computer indicates stops and what to do if a stop is missed, rather than relying on a generic online rule. If you are uncertain about a dive profile, ask a qualified instructor before entering the water.
